Abstract
The invention discloses equipment for detecting internal defects of solar cell strings. The equipment comprises an equipment housing and an operational equipment cabinet. The equipment housing is a cuboid box with a black light-absorption material being adhered to the inner side of the housing. The top of the box is provided with a panel-turnover top cover. A camera assembly and a reflection assembly are disposed inside the box. The reflection assembly is arranged at the bottom of the box and is formed by two flat mirrors of 200mm width. The two flat mirrors form an angle of 90 degrees, and respectively form an angle of 45 degrees with the horizontal plane. The camera assembly is arranged on the top of the box and above the reflection assembly, thus effectively reducing photograph distance of the camera and saving actual space for imaging. Detected cell strings are placed between the camera assembly and the reflection assembly. The invention has the following beneficial effects: 1, defects (such as crack, black chip, broken gate and the like) of cell strings can be detected, and related defect problems of detected cell strings are reflected for quality grading; 2, floor space of the equipment is small; and 3, labor cost is also saved by one man operation for assembly manufacturers.
